36 / 73 page ![]() Smart Machine Smart Decision Table 14: Performance of audio amplifier Conditions Class-AB AMP 4.2V 8Ω THD+N=1% 0.87W 3.4V 8Ω THD+N=1% 0.53W 4.2V 8Ω THD+N=10% 1.08W 3.4V 8Ω THD+N=10% 0.65W SPK2P/2N output can directly drive 8Ω speaker. AT command “AT+CMIC” is used to adjust the input gain level of microphone. AT command “AT+SIDET” is used to set the side-tone level. In addition, AT command “AT+CLVL” is used to adjust the output gain level. For more details, please refer to document [1]. In order to improve audio performance, the following reference circuits are recommended. The audio signals have to be layout according to differential signal layout rules as shown in following figures. 4.7.1. Speaker Interfaces Configuration Figure 31: Speaker reference circuit 4.7.2. Microphone Interfaces Configuration SIM800H&SIM800L_Hardware Design_V2.02 36 2015-07-27 |
